A study of the blood biological constants of the deer “Rusa” (Cervus timorensis russa) in New Caledonia. I. Haematology

Abstract

Since the beginning of year 1987, the deer “Rusa” breeding bas been developing in New Caledonia. In 1988, during a slaughter operation amidst the herds, nearly ninety blood samples were collected in order to define the blood biological parameters (or constants) of this species. Regarding haematology, the study concerns the following parameters: erythrocyte count (9.32x10¹²/L), leucocyte count (4.51x10⁹/L), various leucocyte lines and their formula, i.e. (neutrophile polymorphonuclear: 2.08x10⁹/L [46.6 p. 100]; lymphocytes: 1.75x10⁹/L [38.4 p. 100]; monocytes: 0.33x10⁹/L [7.5 p. 100]; eosinophiles polymorphonuclear leucocytes: 0.4x10⁹/L [7.46 p. 100]; basophile polymorphonuclear leucocytes: 0.01x10⁹/L [0.28 p. 1001), hematocrit (36.8%), hemoglobin ratio (14.1 g/dl), mean corpuscular volume (40.3 dl), mean corpuscular hemoglobin rate (15.3 pg/cell), mean corpuscular hemoglobin concentration (38.7 g/dl). In the course of the study, variations of these parameters were detected according to various physiological criteria and to the sampling conditions as deer is a stress sensitive animal.
